Do You Know Why They Use Purple Paint on Posts and Trees in Texas?

10 different states in the U.S., including the great state of Texas, use the color purple as a warning to trespassers.

Purple shows well in the outdoors. In fact, it’s one of the only colors that color blind people can easily identify. Having said that just seeing it on a fence post or painted on a tree as you go by might only garner a quick glance and an odd look.

No matter what state you are in “posted” and other no trespassing signs can be a headache for landowners to constantly replace. Sometimes they just wear out and sometimes trespassers use them for target practice.

It started in Arkansas in 1989 and by 1997, Texas had adopted the “purple paint rule” as an act of legal legislation. As Jonathan Kennedy, of EastTexasLands.com, says in this video, “The reason they did that is they were trying to keep landowners from constantly having to replace signs.”
